  4. Drizzle garlic butter over roasted cauliflower.
  5. Garnish with parsley and Parmesan, then serve.

Step-by-Step Preparation Method

  1. Preheat Oven
    • Preheat your oven to 425°F (220°C). Line a baking sheet with parchment paper.
  2. Prepare the Cauliflower
    • Remove the leaves and trim the stem of the cauliflower, keeping the core intact.
    • Slice the cauliflower into 1½-inch thick steaks (you’ll get 2–3 steaks per head).
  3. Season the Steaks
    • Place the cauliflower steaks on the baking sheet.
    • Brush both sides generously with olive oil, and season with salt, pepper, and paprika.
  4. Roast the Cauliflower
    • Roast for 25–30 minutes, flipping halfway, until golden brown and fork-tender.
  5. Make the Garlic Butter
    • In a small saucepan, melt the butter over low heat.
    • Add minced garlic and sauté for 1–2 minutes until fragrant (but not burnt).
    • Stir in chili flakes (optional).
  6. Assemble and Serve
    • Drizzle the garlic butter over roasted cauliflower steaks.
    • Garnish with fresh parsley, Parmesan, and lemon juice.

How to Serve This Recipe

  • As a main dish with mashed potatoes, quinoa, or a fresh green salad.
  • As a side dish with grilled meats, roasted chicken, or fish.
  • As a vegetarian entrée, pair with couscous, risotto, or pasta.

Additional Recipe Tips

  • Keep cauliflower slices thick so they hold together while roasting.
  • Don’t overcrowd the baking sheet—this helps cauliflower caramelize.
  • Add a squeeze of lemon juice before serving for extra freshness.

Variations

  • Vegan: Swap butter for extra virgin olive oil or vegan butter.
  • Cheesy: Sprinkle mozzarella or feta before roasting.
  • Herby: Add rosemary, thyme, or oregano to the garlic butter.
  • Spicy: Increase chili flakes or drizzle with hot sauce.

Freezing & Storage

  • Refrigerator: Store leftovers in an airtight container for up to 3 days.
  • Freezer: Not recommended, as cauliflower loses texture when frozen.
  • Reheat: Warm in the oven at 350°F (175°C) for 10–12 minutes to keep crisp.

Special Equipment Needed

  • Baking sheet with parchment paper
  • Sharp chef’s knife
  • Small saucepan (for garlic butter)
  • Pastry brush (for oiling cauliflower)

Frequently Asked Questions

Expand All:

Q1: Can I grill cauliflower steaks instead of roasting?

Yes! Grill over medium heat for 5–7 minutes per side, then add garlic butter.

Q2: My cauliflower fell apart while cutting — what should I do?

Don’t worry. Roast the florets separately; they’ll still taste amazing with garlic butter.

Q3: Can I make this ahead of time?

You can roast the steaks in advance and reheat, but for the best flavor and texture, serve immediately after adding garlic butter.

Q4: Can I use frozen cauliflower?

No, it won’t slice properly into steaks. Fresh cauliflower is best.
